How use pandas dataframe own inside strategy.

[mablue]

Expected Behavior

Hi I need to use pandas dataframe inside strategy cuz I can use functions and libs and etc that can just compute with pandas dataframe.
yes I can convert an np array to what i want but when I want to implemet my own libs them want to use a complit ohlcv format pandas dataframe.
and other problem is that I want to send and use one character column names. ( open = o , close = c ,...) please make ability to send dataframes i df format or I dont know I have many problems with this library but I need this to my work :((((((((((((((((((((((((((((((((
some searches: maybe help
Please Add talib example to your documentation ... also i want to use qtpylib.crossover I dont know how.

bt = Backtest(df, SmaCross,

bt.run()
bt.plot()
